2 8HE ITS-EHELT shell can thus be assembled or applied to one another by a simple telescopic movement in any relative rotative position.

As a means for preventing a relative rota-- tive movement between the cap and shell when applied to eachother, and interlocked in any one of many relative rotative positions to incase the internal mechanism of the socket, I have shown the insulating base provided on its outer end with a plurality of notches or seats, 14, and the shell, 1, cut away opposite said notches, as shown at, 15, to afford free access thereto, and l have formed upon the cap, 3, which is made of sheet-metal, a lurality of inward projections adapted to enter ccrtain of the notches orseats, 14, in any of the many relative rotative positions in which the cap and shell may be interlocked.

As shown in Figs. 1, 2, '3, 5, 6 and S, the inward projections, 16, are formed by in- Wa-rdlydisplacing portions of the cap-wall, said displaced portions being adapted to pass freely through the cutaway portions,

15, of the shell.

As shown in Figs. 4 and 9, the inward projections, 17, are formed by the intro verted ends of a yoke-piece, 18, fixed to the cap, which ends, 17, are adapted to enter the notches, 14, in the insulating base 13. In the form of my invention illustrated in Figs. 4 and 9, it is unnecessary to cut away the shell opposite the notches, 14, in the insulating base.

In the form of my invention illustrated in the other figures of the drawings, as much of the outer end of the shell may be removed as desired to afford free access to the notches, 14.

In both forms of my invention illustrated, Y

the insulating lining, 19, for the cap is secured within the cap by engagement of its outer peripheral edge with the inwardly projecting members, which are adapted to enter the notches in the insulating base to prevent relative rotation of the shell and ca I do not wish to be limited to the particular manner of interconnecting the insulating base, both with the cap and with the shell, as my invention contemplates the use of any known means for interconnecting the cap with the insulating base independently of the shell, and for interconnecting the shell and insulating base independently of the cap, whereby the insulating base constitutes the indirect means for interconnecting the cap and shell so as to prevent a relative ro tative movement therebetween.
